Figure 10 is a View similar to Figure 3, wherein a modified form of the invention is illustrated.

1 of a conventional type, such as generally employed on heavy trucks, busses and the like. The hub I0 is adapted to receive within it a suitable roller bearing and grease retainer, not shown, the bearing and greaseretainer within the hub receiving the outer tapered end of the vehicle axle, not shown. The hub I0 is provided at itsl inner end with 'an annular radially extending flange II having an inner flat face for abutment against the outer flat end I2 of a brake drum I3.

. The brake drum I3 is rigidly securedv to flange I I by a plurality of axially extending studs I4 having heads I5 arranged inwardly of the end I2 of the brake drum as shown. The heads I5- may be riveted or clinched against the end I2 of the brake drum for making the brake drum fast to the flange II. The studs I4 are of course rigidly secured within openings provided for them in the flange I I of the hub. All of this construction is conventional in automotive wheels. The

studs I4 extend axially outwardly of the annular flange II, and are provided outwardly thereof with smooth cylindrical shank portions I6, and outwardly of the shank portions I6 the studs I4 are screw threaded, as at I1, in the usual manner.

Rigidly mounted upon each stud I4 is an inner xed lug I8 having a central axial bore I9 to receive the smooth shank portion I6, which is` tightly pressed into the bore I9. Each lug I8 is generally cylindrical, and has its outer end 20 beveled or inclined at 45 degrees to the'axis 'o fv` its bore I9, as shown." The lugs lare mounted upon the studs in such a Vmanner that the in-` clined ends 20 of the lugs I8 face in the same circumferential direction, Figure 1. The inclined ends 20 face forwardly or lead, when the wheel illustrated in Figure lis turned clockwise. The studs I8 have inner flat circular ends 2! which abut against the outer face of annular flange I I, and the cylindrical sides 22 of the studs VIIl are perpendicular -to the flange II. Each lug I8 is provided upon its cylindrical side 22, and diametrically opposite the inclined end 20, with a pair of axially spaced V-shaped ribs or teeth 23 and 24. The teeth 23 and 24 extend about substantially one-half the circumference of` `the lug l I8, Figures 3 and 5, and form inner and outer cir-r cumferentially extending V-shaped grooves 24 and 25. The inner groove 24 is disposed ad- 3 jacent to the inner end 2|, and in assembly, the inner groove 24' lies next to the outer face of the ange I Figure 3.

The numerals 26 and 21 designate -inner and outer discs of the dual Wheel to be mounted upon the studs I4 having the fixed lugs I8. The discs 26 and 21 are preferably arranged in contacting relation, as shown, and are rigidly secured together by any conventional means. The discs 26 and 21 have registering centralV openings 2S to receive the hub Ill, and are provided with circumferentially spaced registering openings 29, outwardly of the openings 28 for receiving the studs I4 and fixed lugs I8. The openings 29 of the discs 26 and 21 are countersunk on both sides of the discs, for providing annular V-shaped edges or teeth 30 and 3| to engage within the V-shaped grooves 24 and 25 of the lugs |8. As is clearly shown by Figurs 5 and 8, the opening 29 dened by the inner edges of the annular teeth 30 and 3| is of greater diameter than the width of the fixed lug I8 and its teeth 23 and 24, so that when the wheel applied to the hub the openings 29 may engage over the fixed lugs I8. The discs 26 and 21 extend radially outwardly of the brake drum I3 and carry rims 32` and 33, upon which are mounted pneumatic tires 34..

Companion detachablel locking lugs 35 are provided for each stud I4. Each detachable locking lug 35 is generally cylindrical and has its inner end 36 beveled or inclined at 45 degrees to the axis of the stud I4. The outer end 31 of each detachable locking lug 35 is flat and perpendicular to the axis of its associated stud. Each stud -35 is provided upon its cylindrical side and diametrically opposite its inclined end 36 with a pair of axially spaced V-shaped ribs or teeth 38 and 39, forming inner and outer circumferentially extending V-shaped grooves 40 and 4| to receive the annular V-shaped teeth 3G and 3| of discs 26 and 21. In assembly, the V-shaped teeth 38 and 39 of the detachable lugs 35 are disposed diametrically opposite the V-shaped teeth 23 and 24 -of the xed lugs I8, Figure 3. The inclined ends 29 and 36 contact in assembly, and it should be noted that the inclined ends 29 and 36 are parallel to the inner sides of the V-shaped teeth 30 and l3l of discs 26 and 21. The detachable locking lugs 35 are axially shorter than the fixed lugs I8, so that the inner ends 42 of the detachable lugs are spaced slightly from the ange II in assembly, and the outer ends 31 are below the outer ends of the fixed lugs I9, Figure 3. Each detachable locking lug 35 is provided with av central elongated opening or slot 43 of sufiicient width to receive the outer end of a stud I4, and extending axially through the locking lug 35. The openings or slots 43 permit the detachable locking lugs 35 to be shifted laterally with respect to the studs |4 so that the inner ends 36 of the detachable lugs may slide along the outer ends of the xed lugs I3. As shown in Figures 3 and 7, the longitudinal axes of the slots 43 pass through points at the longitudinal centers yof the diametrically oppositely arranged V-shaped teeth 23, 24, and 3|), 3|. Each stud I4 is provided axially outwardly 'of its associated detachable locking lug 35 with -a nut 44, mounted upon the screw threaded portion I1.

In use, the openings 29 of discs 26 and 21 are brought into registration with studs I4 and the fixed lugs I8 carried thereby, and the `openings 29 receive the fixed lugs I8 Within them as Shown in Figure 5. The wheel is now turned manually in the clockwise direction, Figure 1, so that the annular V-shaped teeth 30 and 3| of the discs will be shifted into the circumferentially extending V-shaped grooves 24 and 25 of the fixed lugs I8. This condition is clearly shown in Figures 6 and 9 of the drawings. The detachable locking lugs are now applied to the studs I4 and the inner ends 36 are brought into sliding contact with the outer ends 23 of the xed lugs. The elongated slots 43 of the detachable lugs permit the detachable lugs to slide along the outer ends 29 and to shift laterally in one direction only with respect to the studs I4. Since the ends 20 and 33 are parallel to the inner sides of the annular V-shaped teeth 30 and 3| of the discs, the teeth 39 and 3| will enter the circumferentially extending V-shaped grooves 40 and 4| of the lugs 35, as they are shifted inwardly along the inclined ends 20. This arrangement is clearly shown in Figures 3 and 7. Since the lugs I8 are ixed and the inclined flat ends 20 and 35 are in contact, it is impossible for the detachable lugs 35 to rotate. When all of the lugs 35 are in their positions of Figures 3 and '1, the nuts 44 are tightened and the detachable lugs 35 are forced further inwardly. When this occurs, as is obvious, a wedging and spreading action between the fixed lugs and detachable locking lugs will occur. The annular V-shaped teeth 3G and 3| of the discs 26 and 21 will be driven into the V-shaped grooves at the opposite sides of the fixed and detachable lugs so that the discs become securely locked to the lugs and to the studs I4. The discs 26 and 21 will now have no play or movement in any direction, and when power is applied to the wheel the locking action produced by the lugs is further increased, rather than decreased.

In Figure 10, we have shown a slight modification of the invention, wherein a conventional automobile wheel having a single radially extending web or disc is shown. The automobile wheel of Figure l0 includes a radial hub flange Il',

' identical with the flange II, and studs I4 identical with the studs I4` Nuts 44 identical with the nuts 44 are provided for producing the same wedging and spreading action. Fixed lugs I8 are rigidly mounted upon the studs I4 in the identical manner that the xed lugs I8 are mounted. Detachable locking lugs 35' having elongated slots 43 are mounted upon the studs I4', and co-act with the fixed lugs I8' in the identical manner in which the lugs 35 co-act with the fixed lugs I8. The only difference in the form of the invention shown in Figure 10 is that each of the lugs I8' and 35' is provided with but a single circumferentially extending V-shaped groove 46, for receiving a single V-shaped annular tooth 41 formed by the countersinking of the opposite sides of the single disc 45, adjacent to the openings provided in such disc for the reception of the lugs I3' and 35'. All other parts of the invention illustrated in Figure 10 are identical to those shown and described in the first form of the invention.

It is clearly evident in the forms of the invention shown in Figures 1 to 9 inclusive, and `in Figure l0, that the mounting and locking of the discs 26 and 21 upon the studs of the hub are accomplished by the action of the fixed and detachable lugs which constitute xed and movable wedges respectively. These xed and movable Wedges have the V-shaped teeth, as stated, which constitute parts to interfit with the annular V- shaped teeth of the discs. f

It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the subjoined claims. i
